CAR-SIGNAL.

SPECIFICATION forming part of Letters Patent No. 303,536, dated August12, 1884. Application filed December 253 188 (N model.)

To all whom it may concern Be it known that we, HUGH J. MODEVITT andGEORGE T. BARBER, citizens of the United States, residing atPhiladelphia, in the county of Philadelphia and State of Pennsylvania,have invented a new and useful Improvement in Railroad-Car Signals, ofwhich the following is a specification.

The object of our invention is a signal op- 1 erated by andsimultaneously with the brake of a train of cars in such a manner as togive timely warning that the train has stopped to the engineer of a reartrain, so that he may check the speed of his train or arrest 1 itsmovements in time to prevent a collision; and the nature of ourinvention consists in the arrangement of a lantern or illuminated caseprovided with appropriate signals at each side and at the rear end ofthe last car of the train, and having the danger-signals connected withthe brake-rod by means or cords or chains, so that when the brake isapplied to stop the train the said signals are drawn into position toindicate the fact, and

when the brake is taken off a reverse move ment is given to thesesignals by means of springs, and the white signals are therebyuncovered, as hereinafter fully described. If desired, bell-cranks maybe used instead of 0 pulleys G G G.

In the accompanying drawings,which make a part of this specification,Figure 1 is an end elevation of the rear end of the car A. Fig. 2 is aside elevation of the same.

Like letters of reference in all the figures indicate the same parts.

A represents the rear end of a car, which is supposed to be the last carof a train. It has at each side and at the end wall a lantern orilluminated case, B, which is detachable,

as not being required to be usedin the daytime. For the purpose offacilitating the detachment and connection of the lanterns, they areprovided with hooks a, which engage with the sides I) of the car. Atopposite sides of the lanterns, and in thelongitudinal direction of thecar, there are the ordinary white signals, 0, connected with theopenings in the sides, so that aclear light will be seen at night, thelanterns being illuminated in the usual manner. There are red or dangersignals, 0, hung 011 pins 0, which project from one side of thelanterns. Projecting from the lower edge of the signals are arms (1 d,to which one end of spiral springs D connect, the other 5 5 end of thesprings being fastened to the lan terns, as seen in Fig. 1, whereby thesignals are drawn away from the light into their clevated position whennot under the action of the brake. To arms d (l are connected one end ofthe cordsv or chains G G, which pass over the pulleys E E 011 the end ofthe car, and are connected with the single cord or chain H, whichconnects with the pulley E at the bottom of the car, and extends forward6 5 beneath the same and is connected with the brakerod I, as shown inFig. 2, the connection being made at any convenient part of the rod.

The operationis as follows; WVhen thebrake is applied, the cord or chainH being drawn downward, the cords or chains G G are thereby drawn in thedirection of the arrows, and the signals G O drawn downward, so as tocover the white lights B Band receive lllllllllnation from the lanternsas soon as the train has been stopped by the action of the brake,thereby giving notice by the exhibition of the danger-signal that thetrain is in the way of a train in therear, andthus by giving timely 8Onotice avert acollision. As soon as the brake is reversed to itsinoperative position, the signal-chains being thereby slackened, thespiral springs D D return the signals 0 '0 to their upward position,whereby the white signals O G are exhibited.

We claim as our invention- 1. The combination of the swingingdangersignals O 0, having arms d d, with the white signals 0 O, thedanger-signals being hung on pins 0 c, andconuected with thetension-springs D-D, whereby they are drawn out of line of the white sinals when the force which brings signals down into their lower andillumithem into their normal position is withdrawn, natecl position togive warning to a rear train, IO

substantially as described. substantially as described.

2. The combination of the danger-signals HUGH J. MODEVITT. 5 O 0, havingarms d (l, with the brake-rod I, eords or chains Gr G and H, and pulleysE E and E, whereby the movement of the brakero'd in the stopping of thetrain draws the GEORGE T. BQRBER. \Vitn ess es:
